APPARATUS FOR BURNING GARBAGE.

SPECIFICATION forming part of Letters Patent No. 517,301, dated March 27, 1894.

Application filed December 26, 1893. Serial No. 494.748- (NO model.)

To @ZZ whom t may concer-n: n

Be it known that I, WARD RSLEY, a citizen of the United States, residing at Henrietta, in

- the county of Clay and State of Texas, have invented certain new and useful Improvements in Apparatus for Burning Garbage; and I do hereby declare the following tovbe a f ull,clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in apparatusl for burning garbage, and it consists of certain novel features hereinafter described and claimed.

Reference is hadto the accompanying drawings, in which the same parts are indicated by the same letters and numerals througho'ut the several views.

Figure 1 representsa section of the apparatus along the lines os of Figs. 3, 4, and 5. Fig. 2 represents a section of the device shown in Fig. 1, along the broken line y y of the said ligure, and looking down. Fig. 3 represents a section along the lineze' of Fig. 1, and

looking tothe right. Fig. 4 represents a section along the line e" z ofrFig. 1. Fig. 5 represents a section along the line z2 z2 of Fig. l, and looking to the left, and Fig. 6 represents one of the tubular grate bars detached, bothv vgrates, and also the ends of the lues D and D are supported.

The side walls B and B', and the end walls B2 and B3 are perforated as at b for the purpose of cleaning or trimming the fire, or for man-holes for repairing the various parts of the apparatus.

The crown of the roasting chamber is provided with a plurality of elliptical doors B0, hinged at one side for dumping in the garbage or other matter to be burned. These doors are made elliptical, with their major axes at right angles to the major axis of the roasting chamber as shown so that a large area for dumping in the garbage may be obtained, and at the same time the crown of the arch may be cut away as little as practicable in a longitudinal direction. found that the use of round holes of the same area weakens the crown of the chamber to a material degree.

The grate C for the garbage is made of a plurality of hollow tubes perforated downward as shown at c in Fig. 6, and opening into the outer air. These tubes are screwthreaded on their outer ends as shown at c', and the nuts c2 (see Fig. 4), not only hold the tubes in place, but also strengthen the side walls against bulging outward. It will be seen that these tubes act as tie-bolts for the said walls of the furnace, and greatly strengthen theV same.

D and D are ues which lare supported in the bridge walls B8 and Bgand slope upward so as to assist the passage of the products of combustion from the fire A3. These fines may be of any preferred size or shape, their size varying with the size of the burner.

The top of the burner is covered with sand or other insulating material E, and the ues D and D are wholly or partly immersed in a bed of sand or other suitable non-combusti ble absorbent E.

The operation of the device is as follows:- The garbage being on the grate C, and the fires A', A2 and A3 being kindled, the products of combustion from the fire Apass into the space 1 beneath the grate C, where they receive fresh air sucked in through the hollow grate bars, and through the openings c in the bottom of the same. If an insufficient supply of air be admitted to the fire A', this fire willgive on. large quantities of carbon monoxlide (CO), which uniting with the warmed air coming in through the grate bars C, will continue the ame throughout the space 1 beneath the grate C, and as far as the bridge wall B9. If lthere are any interstices in the garbage, part of the products of combustion will pass up through the grate bars into the space 5, but the bulk of the products of combustion will pass through the openings 2 beneath the grate, then up through the side It has been IOO passages 3, shown in Fig. 5, and through the openings 4: into the space 5 above the garbage. Here they will mingle with the products 0f combustion from the fire A2 and the mixed gases will move above the entire length of the garbage to the opposite end of the furnace, where they will descend through the opening 6 and vertical passage 7, shown in Fig. 3, to the passage 8 above the fire A3. The gases from the fires A and A2 will then `mingle with the products of combustion from the fire A, and the whole passing through the passage 9, will enter the flues D and D', where they will evaporate and destroy any drippings from the grate C. After passing through these upwardly-inclined fines D and D the products of combustion of the three res, mixing with the gases resultant from the burning of the garbage, will pass through the passages l0, 1l, and l2, up the smoke stack 13. It will be seen that the products of c0mbus tion from the fire A', will break up the noxious gases arising from the absorbent mass E', and that these burned gases will mix with the hot products of combustion from the fire A2 and will assist in destroying the foul gases arising from the garbage ou the grate C. Again, should the combined result of the products of combustion from the fires A' and A2, which pass first under and then over the grate, be insuflicieut to complete the destruction of the noxious gases, they are subjected to the heat of a third fire A3 before being ready to be delivered to the open air. These gases, after leaving the fire AB, might be conducted directly to the smokestack without deleterious effects, but itis preferred to carry them through the inclined iiues D and D', so that the heat stored up in the said gases may be partly utilized in evaporating the drippings from the grate C. It will be obvious that artificial means, such as a blower, may be used to increase the draft through the apparatus, if desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. An apparatus for burning garbage and other refuse products, comprising a roasting chamber, a grate supporting the garbage and extending nearly the whole length of the said roasting chamber, a furnace adapted to pass its products of combustion beneath and then above the said grate,a second furnace adapted to pass its products of combustion along the whole length of the top of the garbage grate, a passage for the combined products of combustion from the two furnaces and gases derived from the garbage, a third furnace situated beneath the first furnace and connected with said passage, filles receiving the gases from the three furnaces and the garbage, and leading to the smokestack, and a mass of non-combustible absorbent material surrounding said fines and situated beneath said garbage grate, substantially as and for the purposes described.

2. An apparatus for burning garbage and other refuse products, comprising a roasting chamber, a grate supporting the garbage and extending nearly the whole length of the said roasting chamber, the said grate having hollow grate bars extending across the said chamber with air passages through the bottom of said hollow grate bars, a furnace adapted to pass its products of combustion beneath and then above the said grate, a second furnace adapted to pass its products of combustion along the whole length of the top of the garbage grate, a passage for the combined products of combustion from the two furnaces and gases derived from the garbage, a third furnace situated beneath the first furnace and connected with said passage, fiues receiving the gases from the three furnaces the said fines being arranged horizontally beneath said grate, substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

WARD RSLEY.
